HAP Scholars

About

Each year, the Human Aging Project will work to make research funding available for new HAP scholars according to the availability of funding. Awards will be offered through a call for proposals and an internal application process that targets a specific area of aging research. Applicants targeted are mid-level career faculty in the fields of engineering, basic biology, bioengineering, and clinical translation that wish to develop a project and/or skill set related to aging. Special consideration will also be given to those who work in these named disciplines that focus on health disparities and ways to overcome these disparities. A two page letter of intent that includes background and specific aims, brief approach, and budget will be requested initially.  Send programmatic inquiries to [email protected].

This work includes the development of biomarkers for early detection of AD and to predict postoperative delirium, delirium and cognitive changes after surgery.  Other areas of focus include long-term cognitive changes associated with COVID-19; sensory changes associated with AD; and cognitive impairment in the context of multimorbidities and polypharmacy. As part of her engagement in the HAP Scholar program, she will continue important work on a program to detect delirium risk and provide physicians with delirium interventions for vulnerable patients based on machine-learning algorithms.

HAP Scholars
Hiromi Sesaki, Ph.D.

Hiromi Sesaki, Ph.D.

Hiromi Sesaki, Ph.D., is the 2022 Ethan and Karen Leder CIM/HAP Scholar. Dr. Sesaki is a professor in the Department of Cell Biology at Johns Hopkins University School of Medicine. His laboratory studies mitochrondria, the intracellular energy producers found in most cells. More specifically, he studies mitochondrial fusion and division and mitophagy, an intracellular recycling process thought to be dysregulated with increasing age. Overall, these dynamic mitochondrial processes integrate into major quality control mechanisms that removes mitochrondrial damage and ensures mitochondrial health and robust energy production. As part of his HAP scholars awards, he will investigate how aging influences the mitochondrial quality control mechanism and work closely with other HAP investigators to translate his work into clinical uses related to aging and energy expenditure.

Thomas Cudjoe, M.D., M.P.H.

Thomas Cudjoe, M.D., M.P.H.

Thomas Cudjoe, M.D., M.P.H. is the 2021 Caryl & George Bernstein CIM/HAP Scholar. He is an Assistant Professor of Geriatric Medicine and Gerontology and is investigating a relationship between social isolation and inflammatory biomarkers. His recent findings from a large nationally represented study indicate that social isolation has biological influences and could lead to poor health outcomes such as dementia and premature mortality — a finding of particular import since 1 in 4 community dwelling adults over age 65 are considered socially isolated. Cudjoe’s work points to the importance of developing programs and interventions to address isolation among the aged.

Alexander Pantelyat, M.D.

Alexander Pantelyat, M.D.

Alexander Pantelyat, M.D. is the Alafouzos Family 2021 CIM/HAP Scholar.  He is an Associate Professor of Neurology at Johns Hopkins who focuses on atypical Parkinson’s Disease.  He is also a talented violinist, who with his HAP scholarship aims to make music and rhythm an integral part of treating aging-related illnesses. His studies have shown that interventions such as singing can improve mood, speech, and swallowing in patients with Parkinson’s disease. More recently, in a pilot study of patients with severe (atypical) PD and poor gait, Pantelyat showed that walking to a march-like beat resulted in improved gait and balance — benefits that carried over even after the music stopped. As a HAP scholar, he is working now with an industry sponsor to develop a wearable device — a sensor on the shoe linked to a phone app with a playlist of favorite tunes — that will adjust the music’s tempo to the wearer’s gait. The goal of this program is to give patients with Parkinson’s and other aging-related conditions the opportunity to walk their way to better health at home.
